This is a titty-fucking only exploration horror game. There is no sex other than titty-fucking. All semen built up is destined to go in breasts. You can enjoy the experience of titty-fucking, while remaining safe and sound until the end. The hero is trapped in a deserted hot spring ryokan with his titty-fucking specialist, large-breasted Kouhai. And not only that, there's a problem that you can't even enter the hot springs. You have no choice but to wander the ryokan, to find the cause. Explore various objects to find items, read the left-behind documents for hints, and uncover the incidents and mysteries that had once happened to the ryokan. The large-breasted Kouhai will always follow you, so if you talk to her, you can titty-fuck whenever and wherever you like. At such a hot spring ryokan, aim for some breast-love in the hot springs. It looks like an escape game, but the main element is a casual game where you can titty-fuck at any time.
